View answer and explanation

Correct option: D

\mathrm{R}{\mathrm{b}^ + } < {\mathrm{K}^ + } < N{\mathrm{a}^ + } < L{\mathrm{i}^ + }

Option D (

\mathrm{R}{\mathrm{b}^ + } < {\mathrm{K}^ + } < N{\mathrm{a}^ + } < L{\mathrm{i}^ + }

) is correct because smaller hydrated ionic size leads to greater ease of adsorption on ion-exchange resins.
